To all whom t may concern:

Be it known'that I, ALFRED R. CLARxsoN, a citizen of the United States, residing at Birmingham, in the county of J etferson and State of Alabama, have invented a new and which can be removed and renewed with ease and which can be replaced, without eat expense, by various other sizes of jet orming portions, if desired. I attain these and many other desirable objects, which will appear, by means ofmy invention one practical embodiment of which is shown'in the accompanying drawings and described in this speciiication.

Figure l is a section of my nozzle taken longitudinally through the center line of the nozzle. Fig. 2 is a section of my complete nozzle in its preferred form taken on the line A-A of Fig. l. Fig. 3 is a similar section to Fig. 2 of a modification of my device.

Similar letters refer to similar parts throughout the several views.

The part 5 consists of a nipple threaded externally at each end as at 7 which may be of any desired metal preferably brass or hardened bronze. The cylindrical passage 8 of thenipple extends for a short distance through the nipple and then merges, by means of the conical passage 6 through the partitioning projection, into another cylindrical passage extending the remainder of the way through the nipple. In the latter cylindrical assage is located a short length of glass tu ing having extending through its length a passage 3 the size of which determines to a great extent the size of the jet of fluid passed therefrom. This glass tube is held within the nipple by means of the cap l in which there is a hole 2 preferably of somewhat larger diameter than the cylinr following is a l drical passage 3 in the aforementioned glass tube 4. As shown in Fig. 3, the nipple 5 may be square, if desired, having its opposite ends rounded and threaded. l prefer, however, to have the nipple cylindrical as shown in Fig. 2.

By means of the conical reduction of the bore of the nipple 5 as shown at 6 I bring the size of the bore down to almost the size of jet desired and also form the shoulders against which the glass tube rests when in place.

The hardened glass tubing may be very easily procured in short lengths at a very much lower cost than special glass shapes and the hole therein formed is quite accurate, smooth and has walls which will not rust or be easily worn. Furthermore the glass may be used with a great many liquids used as disinfectants where metal would be of no value. The length of the glass tube should be at leastthree times the diameter of its orifice to form the best jet. By making the hole in the glass of cylindrical shape, without a bell mouth, it may be reversed, if desired, for cleaning or other purpose. If a larger or a smaller jet is` deslred, the exchange may be easily effected by removing the cap l, withdrawing the tube 4; and inserting another glass tube having the same outside diameter but having a different bore. As the bore of the glass tube determines to a great extent the size of the issuing jet, it is apparent that wear of the metal parts may be very appreciable without adecting the size of the issuing jet. This featureof the nozzle is of great importance in humidifier or moistening apparatus where water under from fifty to two hundred pounds pressure per square inch is sometimes used, especially if the water contains grittyvmatter in suspension. Under such conditions a hardened steel jet or nozzle would last but a few months, and then the size of t-he bore would appreciably increase and the air would not be able to carry oit the additional amount of water t being loose 'in the sense that it is not ce` mented or forced into the metal, may easily and quickly be replaced, if desired for -any reason. It is, of course, apparent that other vitreous substances or such substances as hardened and glazed porcelain may be substituted for glass and be, in some respects, of the same value in this connection.

I do not, of course, desire to limit myself l to the exact 'details of construction of the of'said partition being of substantially the same diameter, and an opening through said partition.

lf2..l A nozzle comprising a tube, a cylindricalglass block within said tube, a partition projecting within the bore of said tube and a perforated cap holding said block against sa1d partition, substantially as described.

9 3.' As an article of manufacture, a nozzle comprising a nipple threaded externally on each end and having an interiorl shoulder in the bore thereof, a glass tube of substan# tially the same bore throughout loosely lodged in said nipple and a cap holding said -l glass tube against the shoulder within said nipple.

4.-.' As an article of manufacture, a nozzle 'comprising a nipple having a-shoulder integral therewith and projecting intoY the l.

bore thereof and a removable and reversible cylindrical glass block having a bore of substantially the same diameter throughout and lodged against said shoulder and a cap fastened `to said nipple and retaining said A glass block in position, as 'and for the purpose specified.

5. A nipple having a chamber, a removable cylindrical block illing said chamber,

and means contacting with the end of the nipple and block and retaining the block in position.

In testimony whereof I hereby aiix my signature in the presence of two subscribing witnesses.

ALFRED R. GLARKSON.
